Abstract
The invention relates to an electronically commutated electric machine (2) comprising: a rotor (21); an exciting winding (6) that is located at the rotor (21) in order to generate or alter a direct magnetic field in the rotor (21); a stator (22) comprising a three- or multi-phase stator winding (23) with phases that can be controlled via phase lines (8). The exciting winding (6) is connected to the stator winding (23).
Claims11
An electronically commutated electric machine (2), comprising:
- a rotor (21);
- an exciter winding (6) arranged at the rotor (21) in order to generate or alter a direct magnetic field in the rotor (21);
- and
- a stator (22) having a three-phase or polyphase stator winding (23) with phases which can be driven via phase lines (8);
- wherein the exciter winding (6) is electrically connected to the stator winding (23).
